IMPROVEMENT IN APPARATUS-FOR MANUFACTURING citnsesrz.

The Schedule referred to :in these Letters Patent and making part of tho same.

` eral parts of the apparatus used in the improved manufacture of cheese.

Figure 2, plate 2, is a vertical section, through the cheese-vat, curd sink, and the pipes ywhich conductair into the body of the milk iu thcfvat for cooling the Figures 3, 4, 5, and 6, plate 2, showing modo of constructing that part` of the apparatus which is used for heating water. i

Figure 7, plate=.2, is a top view of the cheese-vat.

Similar letters of reference indicate. corresponding plrts in the several iigurcs.

This invention relates to certain novel improvements which will. facilitate the process of cheese-making.

Preparatory to commencing the process of curdling milk, it is necessary to deprive itot its animal heat and odors, and keep it in motion to preventthe cream from rising.

'.lo effectthcse objects, the nature of my invention consist-s- Y "First, in Ycombining with one or morev curdling-vats a cool-watcrfsupplying apparatus, and an air-supply-y ing apparatus, constructed and applied as will be hereinai'tcrexplained.

,During the process of curdling the milk. it is necessary to applyheat to it, and for this purpose the nature ofmy invention consists, secondly, in a water-heating appara-tus, which will supply warm water beneath the curdliug-vat or rats, and w hich is supplied automatieallyf with cool water as rapidly as the heated water is conveyed off to the vat or vats.

After curdling it is desired to quickly dry and purify the cui'd, und to this cud the nature of my invention consists, thirdly, in providing for the introduction of pure cool air beneath the rack in the curdsink, by means'of the same air-supplying apparatus which is used for forcing air into the curdling-vat, as willbe hereinafter explained.

To enable others skilled in thel art to understand 4my invention, I will describe its construction aud operation.

For the purpose of facilitating the description of my apparatus, I havercprcsented, in tig. 1, theI several part-s composing it as they would appear if arranged within one room or apartment; hut in practice I shall .locate the water-supplying apparatus in an apartment separate from the manntacturiiig-room, for the purpose of avoiding in'this room the heat, dirt,`and steam which rise from the said apparatus when it is necessary to heat the water therein.

. lf desirable, the bellows or airsnpplying apparatus may also be located in au apartment separate from the manutcturing-room, for the purpose of having the air which is forced through this z i.1.)paratus pure and cool.

The water-supplying apparatus consists of a chamber of any suitable capacity, surrounded h v walls C,

.and adapted for containing water. y

Within this chamber, and located near the bottom thereof, is a fire-box, M, horizontally arranged, and provided with a iced-door, a, for supplying fuel.

From the back or rear end of this tire-box M, smallue-pipcs b l) extend, which are carried upward and out through the top wall into a main tlue or chimney, C, for the purpose of conducting oli" the spent productsof combustion.

The pipes or fines '1) aii'ord a very largo amount of hcating-sin'tiice, and communicate considerable heat to the watersurroumling them in thc chamber surrounded by walls (l.

For the purpose of keeping chamber (l properly supplied at all times with water, a pipe, c, lea-ds from a reservoir, spring, or other buutain-head, which is located above the level of said chamber, at its upper end, and is provided with a lioating cut-ofi', consisting of a vertically-vibrating arln, R, having afloat, O, on its free end, and a plug or valve, s, so arranged with reference to the discharge'eml of said pipe c that the water will be maintained at a uniform height in the chamber C.

Another form of heating-appara-tus may be applied within the chamber C, instead of the one above described. This is shown in Iigs. 5 and, and consists of a tire-chamber, M', made of cylindrical or other form, and arranged horizontally in said chamber C; with a chimney or tlne-pipe, C2, leading up through the top wall of said chaniber, for conducting ofi' the products ot' combustion.

L1n this heater the flame is brought in direct contact with dialuetricallyrarranged pipes b 11, which prevent mucl ot' the central heat from escaping up chimney C2; and each one ofthesepipes bis provided with a short wooden pipe, y, whichis pertbratcdwit-h small holes, and which is connected to a longitudinal wooden pipe, p, that communicates with .a distrilmting-pipe, 1)', which conveys water to pipes leading to the curdlin'g-vat or vats. n

'lhe short perforated pipes y do not t tightlyin thc cross-pipes b', but spa-ces are allowed around them for currents .of water to circulate freely and enter these pipes y, through their pertbratious. g

By this arrangement of pipes, n constant stream of watercan bedrawn from the chamber C through the distributing-pipes; and when heat is .applied in the fire-box M', the water will be warmed by contact with the' sides of thisbox, and au extra amount` of heat will be communicated to the water while drawing it oli", by causing the currents to enter the cross-pipes b' betbre escaping into the pipes y.

The pipes y p may be made of `wood or metal, but 'I' prefer the wood, as it is a good non-conductor of heat, and will not corrode.`

While I prefer to employ the heating-apparatus last described, on account of economy of fuel and equality of beat communicated to the water, I do not confine myself to vthis precise construction of heating-apparatus.

'lhedistributing-pipe D' communicates with a pipe, D, which may be made of wood, or made of met-al and enclosed by a poor conductor of heat, and which leads oli to a funnel, it, applied to a tank, E, containing the curdling-vat F.

Water is discharged' into the funnel n, from pipe .1),

by means of a short nozzle, d, shown in iig. and this funnel leads down into a pipe, P, from which short branch-pipes t extend, as indicated in dotted lines,

` The pipe P and its branches tare thickly perforated, and are arranged within a space enclosed by thewallsv of the curdling-vat 1"l and its tank E, and located beneath said vat, so as to afford a bottom support for it.

The vat F is secured, by its upper flanged edges, to a removable frame, E', which fits snugly on top of the tank E, and is held in place by the upper extensions of the standards which 'support this tank, as shown in fig 1.

, 1f several curdling-vats are used, they will be provided with tanks supplied with water from the 4chamber C, as above described for the single tank.

Before proceeding further with my description, I will stat-e that for the purpose of supplying water to cool the milk in vat or vats F, preparatory to the curdlingprocess there is no fire made in the fire-box consequently cold water will iiow through the distributingpipes and beneath the curdling-Vat or vats. The water is only heated during the process of curdling.

In combination with the tank F, and also with al curd-sink, I, I also employ an air-supplying apparatus.' rlhis may consist of bellows B, or other suitable airforcing pump,'which is supported by a frame, A, at a suitable height to be out of theway, and from its nozzle B air is conducted into an oscillating pipe, G, or into branch-pipes or hose H, or into both.

The pipe G is arranged in a horizontal plane over the centre of the vat F, and supported, at its closed end, by a pendant, A', and at the opposite end by a pipe, f, and flexible tube L.

The flexible tube L is used to allow pipe G to be oscillated by a rod, K, proceeding from the arm N of the bellows, but instead of this tube L any other tight- .joint connection may be adopted which .will operate in` a similar manner.

The rod K being fastened at one end to the bellowsarm N, and atthe other end to the pipe G, it will be seen that this pipe will receive an oscillating motion' at the same time the upper leaf of the bellows is operated to force air into this pipe.

It' it is desired to have the pipe G remain stationary while the bellows are being operated, the rod K may be detached from arm N.

From the pipe G, air is forced into the body of milk in vat'F, through pendent pipes, which will also serve the purpose of agitators during the process of cooling the milk.

Each one ofthe pendent pipes consists of a section,

S, made fast to pipe G, a pipe, T, which reaches into the milkin vat F, anda exible lcoupling, c, which unites the sections S T, and allows the lower section T to be removed at pleasure,

The lower sections T may be made of wood,'metal, or glass, with their lower ends perforated, to allow the air to .escape into t-he body of milk'in vat F.

vThe air-pipes H, which-lead into the curd-siuk I, may beprovided with cocks for shutting off the flow of air through them when it is desired to force all the air into the vat F; and the pipe f may also be pro.- vided with a cock for shutting olf the flow of air to the vat F, when it is desired to force all the air into the card-sink. I

"c'Ihe cord-sink consists of a box, I, mounted ,upon

legs, and provided with a removable rack, J, upon which latter the, eurd is worked in the usual wellknown manuel'.

The pipes H H lead into thel ends of the sink I, be-I neath the rack J, and'allow the bellows B to force air in such quantities upward -through the rack J as to cool and purify thee-11rd while it is draining` and being worked.

'Ifhevbellows will also serve as a means forv cooling and pnriiying'the air of the manufacturing apartment during hot and sultry weather, by furnishing pure, cool air lin abundance to this apartment.

1t will be seen from the above descript-on'that during the process of cooling, the milk, and depriving it of its animal odors', I am enable-d to use in large quantities cool water, regulated in its flow and distributed uniformly over the bottom of the vat F, and that during this cooling-process I introduce pure cool air into the body of4 milk in said vat, and at the same time agitate the 'milk to prevent the cream from rising or separating.

I also employ the air-forciug bellows for the purposev of forcing'iair 'under the rack of the card-sink, and thus cooling and purifying the particles of cu'rd while being worked and drained of whey.

Having'described my invention,

lVh'at I claim as new, and' desire to secure by`Letters Patent, is-

1. rPhe combination of the automatic device R, or its equivalent, the water-snpplying pipe c, vat-tank E, and funnel 11, substantially as described.
